Bayesian Decision Trees Inspired from Evolutionary Algorithms

no code implementations30 May 2023 Efthyvoulos Drousiotis, Alexander M. Phillips, Paul G. Spirakis, Simon Maskell

Bayesian Decision Trees (DTs) are generally considered a more advanced and accurate model than a regular Decision Tree (DT) because they can handle complex and uncertain data.

Parallel Approaches to Accelerate Bayesian Decision Trees

no code implementations22 Jan 2023 Efthyvoulos Drousiotis, Paul G. Spirakis, Simon Maskell

None-the-less, we propose two methods for exploiting parallelism in the MCMC: in the first, we replace the MCMC with another numerical Bayesian approach, the Sequential Monte Carlo (SMC) sampler, which has the appealing property that it is an inherently parallel algorithm; in the second, we consider data partitioning.

Adaptive Bayesian Beamforming for Imaging by Marginalizing the Speed of Sound

no code implementations7 Dec 2022 Kyurae Kim, Simon Maskell, Jason F. Ralph

Imaging methods based on array signal processing often require a fixed propagation speed of the medium, or speed of sound (SoS) for methods based on acoustic signals.

Data-driven clustering and Bernoulli merging for the Poisson multi-Bernoulli mixture filter

no code implementations27 May 2022 Marco Fontana, Ángel F. García-Fernández, Simon Maskell

This paper proposes a clustering and merging approach for the Poisson multi-Bernoulli mixture (PMBM) filter to lower its computational complexity and make it suitable for multiple target tracking with a high number of targets.

Efficient Learning of the Parameters of Non-Linear Models using Differentiable Resampling in Particle Filters

no code implementations2 Nov 2021 Conor Rosato, Vincent Beraud, Paul Horridge, Thomas B. Schön, Simon Maskell

It has been widely documented that the sampling and resampling steps in particle filters cannot be differentiated.

An analysis on metric-driven multi-target sensor management: GOSPA versus OSPA

no code implementations22 Oct 2021 Ángel F. García-Fernández, Marcel Hernandez, Simon Maskell

On the contrary, as a consequence of the spooky effect at a distance in optimal OSPA/UOSPA estimation, the optimal actions for different sensors using OSPA and UOSPA are entangled.

Reliability Validation of Learning Enabled Vehicle Tracking

no code implementations6 Feb 2020 Youcheng Sun, Yifan Zhou, Simon Maskell, James Sharp, Xiaowei Huang

However, it is unclear if and how the adversarial examples over learning components can affect the overall system-level reliability.

Detecting and Tracking Small Moving Objects in Wide Area Motion Imagery (WAMI) Using Convolutional Neural Networks (CNNs)

2 code implementations5 Nov 2019 Yifan Zhou, Simon Maskell

This paper proposes an approach to detect moving objects in Wide Area Motion Imagery (WAMI), in which the objects are both small and well separated.
